Application August 30, 1937, Serial No. 161,646

2 Claims.

This invention relates to closures, and its general object is to provide a closure that is capable of fitting the mouths or open upper ends of jars and like receptacles, with or without necks, and of various diameters, for closing and sealing the same.

A further object is to provide a sealing closure for jars that can be applied and removed with respect thereto, in an easy and expeditious manner, without destroying the sealing means, yet will set up a positive sealing action when in applied position, under all conditions, as accidental displacement or removal of the closure is practically impossible.

Another object is to provide a sealing closure for jars and the like, that is simple in construction, inexpensive to manufacture and extremely emcient, in operation, use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure l is a vertical sectional View taken through my closure and illustrates the same applied to a jar of the straight, vertical, cylindrical wall type.

Figure 2 is a top plan View of the cap.

Referring to the drawing in detail, it will be noted that I have illustrated my sealing closure as being applied to a jar l of the straight vertical cylindrical wall type, but it can be applied with equal efficiency to a jar having a neck which is plain or exteriorly screw threaded.

My closure includes a cap 2 which is preferably made from glass or like material, to provide a relatively thick disk like body that has formed on the upper and lower surfaces thereofl, a plurality of annular steps providing shouldered portions 3 and 4 respectively and which decrease in diameter from the outer edge of the body inwardly, as clearly shown in Figure 1. It will be further noted from Figure 1 that the diameter of the upper shouldered portions 3 differ from the diameters of the lower shouldered portions 4, with the result it will be obvious that the capis reversible, so that it is capable of fitting the mouths or open upper ends of jars and like receptacles of various diameters, in that the periphery of any one of the shouldered portions is seated within the mouth or upper end of the jar as shown in Figure 1, with the body or outer adjacent shouldered portion overlying the upper end. Disposed between the upper end of the jar and the cap is a gasket 5 to provide a seal, it being apparent that gaskets of various diameters are used to fit the shouldered portions.

In order to hold the cap sealed on the jar, I provide clamping means which include an inverted substantially U-shaped member having an upper wall 6 with side walls 1 formed on and depending therefrom in parallel relation with respect to each other, and bridging the side walls 1 and fixed thereto are pins 8 arranged in companion pairs and one above the other in superposed relation, to receive the end portions of a strap or band 9 which is preferably formed from metal and is disposed about the jar to contact the cap upon diametrically opposite sides thereof.

The end portions of the band are looped about .10 the pins 8 in a manner to be clamped thereto, as shown in Figure l, and the upper wall 6 is pro-- vided with an interiorly threaded opening reinforced by aboss IE! and which has threaded therein a thumb screw ll provided with a shank having a pointed outer end.

The outer shouldered portions may each be centrally thickened as at 12 but I have illustrated a central thickened portion on one outer shouldered portion only, and the thickened portion I2 is preferably circular for the purpose of receiving a disk washer l3 of rubber that has mounted thereon a metallic washer H! for disposal in the path of the pointed end of the shank of the thumb screw II, with the result it will be obvious that the cap is held in sealed position with respect to the jar through the instrumentality of the thumb screw, its carrying member, and the band.

To facilitate the removal of the cap from the jar, when the clamping means is removed therefrom, I provide a minute bore I5 extending centrally through the cap and which is closed by the rubber washer [3. However, it will be obvious that when the washer is removed, or a hole is punched therein to register with the bore l5, that the partial vacuum which is formed in the jar will be destroyed, thereby allowing free removal of the cap.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is:

1. A jar closure comprising a cap, stepped shouldered portions on said cap to fit jars having upper ends of various diameters, sealing means of various diameters to fit the shouldered portions for disposal between the jar and cap, clamping means including a band for disposal about the jar and upon diametrically opposite sides of said cap, means including superimposed pins arranged in spaced pairs for detachably and adjustably receiving the end portions of the band to be looped about the pins in clamping association therewith,

and screw means to bear. against the capand co- 1 2. A jar closure comprising a cap, stepped shouldered portions upon the upper and lower sides of said cap to fit jars having upper ends of various diameters, sealing means between any one of said stepped shouldered portions for disposalbetween the jar and cap, clamping means including a band for disposal about the jar and engageable with the cap upon diametrically opposite sides thereof, an inverted substantially U-shaped member including an upper wall and parallel walls. depending therefrom, superimposed pins arranged in pairs and bridging the depending walls, said pins receiving the end portions of the band for clamping association therewith, abutment means mounted on the cap, and a thumb screw extending through said member and engageable with the abutment means for drawing the band taut to secure the cap in sealed position.
